This would be pump number three.

Why yes, moving parts wear out despite any advertising hype to the contrary.

To my serious lack of astonishment, each version is more flimsy than the previous one, and, as far as I can tell, the tubes are not backward compatible despite pump two and pump three theoretically being the same model.

Joy.

Somebody who sold a pump with user-replaceable parts at 150% of the cost of the others would clean up. "Look, any pump will break before you're done using it. Wouldn't you rather be using one that's *repairable* for 1/5 the cost of a new pump?"
